for loop

Question

Usually, for loops look something like this:
for(x=0;x<10;x++)
But wht do some for loops look like this?
for(int y:x)

Answer 1

That's a C++ simplification of looping similar to 'for each' in other languages.

Int y declares the type of each item, x in this case would be a collection like vector.

Then you can just do whatever you want to do with each y.
